GAS LINE
INSTALLATION
Since some municipalities have additional local
codes it is always best to consult with your local
authorities.
When using copper or flex connectors use only
approved fittings. Always provide a union so
that gas lines can be easily disconnected for
servicing. Flare nuts for copper lines and flex
connectors are usually considered to meet this
requirement.
NOTE: A shutoff valve should be supplied
in or near the unit (or as per local codes) for
ease of servicing this appliance.
Regency GF900L-1 Gas Fireplace
PILOT ADJUSTMENT
1.13 kpa
Periodically check the pilot flames. Correct flame
0.4kpa
pattern has two strong blue flames: 1 flowing
around the flame sensor and 1 flowing across
the burner (it does not have to be touching the
0.87 kpa
burner).

25 MJ/hr
35 MJ/hr
Note: If you have an incorrect flame pattern,
contact your Regency
instructions.
Incorrect flame pattern will have small, probably
yellow flames, not coming into proper contact
with the rear burner or flame sensor.
GAS PIPE PRESSURE
TESTING
The appliance must be isolated from the gas sup-
ply piping system by closing its individual manual
shut-off valve during any pressure testing of the
gas supply piping system at test pressures equal
2.75 kpa
to or less than 3.45 kPa. Disconnect piping from
1.6 kpa
valve at pressures over 3.45 kPa.
The manifold pressure is controlled by a regulator
2.49 kpa
built into the gas control, and should be checked
at the pressure test point.
#53 DMS
Note: To properly check gas pressure, both
23 MJ/hr
inlet and manifold pressures should be
28 MJ/hr
checked using the valve pressure ports
on the valve.
1) Make sure the unit is in the "OFF" position.
2) Loosen the "IN" and/or "OUT" pressure tap(s),
turning counterclockwise with a suitable wide
flat screwdriver.
3) Attach manometer to "IN" and/or "OUT" pressure
tap(s) using a suitable ID hose.
4) Turn the unit on with the remote or wall switch
5) The pressure check should be carried out with
the unit burning and the setting should be within
the limits specified on the safety label.
NOTE: All the adjustments must be carried out in
the following order:
Remove the modulator plastic cap (A) using
needle nose pliers.
Maximum pressure: Turn the unit ON to its highest
input rating. Screw in the nut (B) to increase the
outlet pressure and screw it out to decrease it.
Use a 10 mm wrench.

installation
NOTE: The outlet pressure must be set to maximum
2.49 kPa for both LP/ULPG and 0.87 kPa for NG.
Minimum pressure: Remove one of the cables co
nected to the electric modulator. While holding the nut
(B) with a wrench, screw in the screw (C) to increase
the pressure and screw it out to decrease it. Use a
screwdriver 6x1 blade.
After carrying out all adjustments, block the setting
screws with paint, taking care not to obstruct the
breather orifice of the pressure.
Put back the modulator plastic cap.
WARNING: To ensure the correct operation of the
modulator it is necessary that the plastic cap (A) is
returned to its original location.
NOTE: The outlet pressure must be set to
minimum 1.6 kPa. for both LP/ULPG and
0.4 kPa for NG.

6) Turn on gas supply and plug in power cord.
7) At the end of all setting and adjustment operations,
check electrical installation and gas leaks.
8) Check operation of flame control.
9) Check for proper flame appearance and glow on
logs.
10) When finished reading manometer, turn off the
unit, disconnect the hose and tighten the screw
(clockwise) with a suitable flat screwdriver.
Note: Screw should be snug, but do not over
tighten.
